Event kinematics and energy flow are investigated in deep inelastic dijet events at low values of Bjorken-x. A measurement of the differential dijet cross section as a function of the fractional photon momentum x_gamma is presented. The analysis is based on an integrated luminosity of 1.962 pb-1 taken with the H1 detector at the ep storage ring HERA in 1994. Monte Carlo predictions using direct photon interaction, matrix elements, and DGLAP or CDM parton cascades fail to describe the data. Such models underestimate the dijet cross section as well as the energy flow outside of jets in the photon direction. Including an additional contribution of the resolved virtual photon with matrix elements and DGLAP parton showers leads to an improved description of the data.
